Matricaria aureais an important medicinal plant belonging to Asteraceae, the widely used in the phrmacetical, food and cosmetics industrial. According to importance of this plant, the aim of current study was optimizing tissue culture in Matricaria aurea. In order to optimize of tissue culture two experiments, callus induction and indirect regeneration were carried out. These experiments were laid out in factorial arrangement based on completely randomized designs (CRD) with three replications on MS base medium. In these experiments, various levels of plant growth regulators, NAA (0, 0.5, 1and 2 mg/l) and BAP (0, 0.5, 1and 1.5mg/l), with two explant types (stem and leaves) were compared. The results showed that was not observed in growth hormone-free medium (control). Results showed that callus induction was occurred fast in all explants in combination of NAA (0.5 mg/l) and BAP (1 mg/l). The best combinations of plant growth regulators for callus induction were 0.5 mg/l NAA + 1 mg/l BAP and 1 mg/l NAA + 1 mg/l BAP for stem and leaves (100%) respectively. Interaction of different concentration of NAA and BAP was significant for callus diameter trait and leaf explant in combination of 2 mg/l NAA + 1.5 mg/l BAP was the highest callus diameter with mean of 15.31 mm. We observed maximum of indirect regeneration percentage (85.59%) in calli derived from leaf in medium with 0.5 mg/l NAA + 1 mg/l BAP.
